Comment 34 for bug 333730

Here's my experience so far in relation with this bug, on a HP DV5-1124CA laptop, with an Atheros AR928X card:

1. Out of the box, the ath9k driver provided by Jaunty and Karmic give really unstable and weak connections. In my case, installing the linux-backports-wireless-modules-karmic improves things dramatically (it gives me a quite stable and strong connection), while there are still the issue described at point 2.

2. The remaining greatest issue is caused by what I understand to be the periodic scanning operations of network-manager, which causes some connections interruptions/hangs . See these reports:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/414560

I have managed to circumvent this issue, by opting for one or the other following solution:

a) using wicd instead of network-manager
b) using ndiswrapper, instead of the ath9k module, with the latest windows XP driver available on this page (in my case : http://www.atheros.cz/
